Title

Nama Group geochemistry (NERC grant NE/I00596X/1)

Abstract

Rare earth element, major and minor element, and iron speciation data for nine independent sections in the Nama Group, described in detail in Wood et al., 2015, Precambrian Research, and Tostevin et al., 2016, Nature Communications. Additional data for Zebra River section include sulfur isotopes from carbonate associated sulfate (published in Tostevin et al, 2017, Precambrian Research); Uranium isotope data for carbonates (published in Tostevin et al., 2019, EPSL); Calcium isotope data for carbonates (unpublished).

Methodology used to collect REE data is described in detail in Tostevin et al., 2016, Chemical Geology. In brief, a sequential leaching procedure was used on the samples, with the first 20% discarded and the next 40% retained. Methodology used to collect iron speciation data from carbonate rocks is detailed in Clarkson et al., 2015, Chemical Geology.
